I removed all sys.path customizations and rebooted.

In the following scenario, I am programming in one.py attempting to
import Data.py which is in the alpha folder:

However, all I can get is error:

    from .. import Data
ValueError: Attempted relative import in non-package

Why is the parent folder not recognized as a package? Because right
now I am liberally using sys.path, which works but is a little too
messy.
